FLORENCE KROEBER, OF NEW YORK, N. Y.

ALARM-CLOCK.

SPECIFICATION forming part of Letters PatentNo. 228,202, dated JuneApplication filed April 6, 1880.

To all whom it may concern:

Be it known that I, FLORENCE KROEBER,

I of New York city, in the county and State of New York, have inventedan Improvement in Alarm-Clocks, of which the following is aspecification.

My invention relates to improvementsin the arrangement of the bell forsounding the alarm and the connection of the movement with the bell; andthe object of the invention is to so arrange the bell that it will besituated outside of the case instead of inside, as heretofore.

The invention consists in connecting the bell with a crank-shaft placedin an ornamental figure above the clock and conuectin g the hammer-tailwith the crank-shaft thus arranged, whereby the alarm-movementcommunicates through the hammer-tail the vibratory movement to theshaft, and thereby vi brates the bell and sounds the alarm.

The invention also consists of details of construction and arrangement,which will be fully described fart-her on in the specification.

In the accompanying drawings, Figure 1 represents a front elevation ofmy improved alarm-clock. Fig. 2 represents a vertical section throughthe center of the figure and a part of the clock-case on a planeparallel to the face of the clock. Fig. 3 represents a longitudinalsection of the bell, showing the manner of connecting it with the handof the figure.

Referring to the drawings, A represents the face of the clock; B, theshellor case, of suitable form; C, the alarm-movement; a, theescapement; D, the hammer-tail.

E represents the figure'standing on a base, F, which is placed over anopening, G, in the shell just over the alarm-movement. The said base Fhas on each side ears I), which rest on the shell 13, and are connectedwith the said shell by screws or other suitable devices, whereby theopening Gr in the shell or case is completely covered in, and the figureE is firmly attached to the shell or case of the clock. The figure E andbase F are hollow, and, it will be observed, are made in two parts, cl6, the two parts being put together so as to conceal as nearly aspossible the joint, and connected by screws or in any other suitable (Nomodel.)

manner. In part displaced the crank-shaft K in suitable bearings f. Oneend of the crank-shaft projects out of its bearing f, and is connectedto the arm H of the figure. The hammer-tail D extends from theescapement a to the crank-shaft K.

When the movement 0 operates the vibratory movement of the escapement ais communicated through the hammer-tail D to the crank-shaft K, which isthereby vibrated and communicates the vibratory movement to the arm H.

I represents the bell. The clapper g is pivoted to the screw-shaft h,which is passed through the hand 2' and secured by a nut screwed on itsprojecting end. The bell is thus attached to the vibrating arm H, andpartakes of its movement.

\Vhen the escapement a is vibrated the motion is communicated throughthe hammertail D and crank-shaft K and arm H to the bell I, and when thearm H moves in obedience to the action of the escapement, the bell beingvibrated, the alarm is sounded by the bell I.

I have described the invention as applied to the arm of therepresentation of a human figure; but it is evident that the design ofthe figure E may be materially varied without depart-in g from thespirit of this invention.

I claim- 1. The combination of the hammer-tail D of an alarm-clock withthe crankshaft K, vibrating arm H, and vibrating bell I, substantiallyas described.

2. In an alarm-clock, the hollow figure E, in combination with thehammer-tail D, crankshaft K, vibrating arm H, and vibrating bell I,substantially as described.

3. The hollow figure E, with the crank-shaft K, vibrating arm H, bell I,and base F, in combination with. the case or shell B of the clock,provided with the opening G, substantially as described.

4-. The bell I, having clapper g and screwshaft h, in combination withthe hand z'and vibratory arm H, substantially as described.
